将数组字符串转成字符串数组

// 将 数组字符串 转成 字符串数组
public static void main(String[] args) {
    // 数组字符串
    String str = "[\"data1714124309028622336\", \"data1714124435671437312\", \"data1714124761333977088\"]";

    JSONArray jsonArray = JSON.parseArray(str);
    Object[] arr = jsonArray.toArray();

    for (Object s : arr) {
        System.out.println(s);
    }
}

将数组字符串转成字符串 List

// 将 数组字符串 转成 字符串 List
public static void main(String[] args) {
    // 数组字符串
    String str = "[\"data1714124309028622336\", \"data1714124435671437312\", \"data1714124761333977088\"]";

    List<String> stringList = JSON.parseArray(str).stream().map(Object::toString).toList();

    for (String s : stringList) {
        System.out.println(s);
    }
}
